CARTRIDGE.

SPECIFICATION forming part of Letters Patent No. 249,301, dated November8, 1881.

Application led February 18, 1881 To all whom it may concern Be it knownthat I, WILLIAM T. CHAMBER- LAIN, a citizen of the United States,residing at Norwich, in the county of New London, State of Connecticut,haveivented a new and useful Improvement in IVads, which improve ment isfully set forth in the following specitication and accompanyingdrawings, in which- Figure 1 is a side elevation ot' a wad embodying myinvention. Fig. 2 is aface View thereof. Fig. 3 is a longitudinalsection illustratingthe wad in position in a barrel. Fig. 4 is alongitudinal section of the wads in position in a cartridge. Fig. 5 isalsectional View ot one ofthe wads.

Similar letters otl reference indicate corresponding parts in theseveral figures.

My invention consists of'awad of the form of an annulus, the opening ofwhich is cylindrical, so that the wall of either end thereof coincideswith and is adapted to abut against the ball, a wad being employed infront and rear of the ball, and a solid wad interposed between the rearwad and the powder. By this construction the ball will be centered anddischarged true and'eiiective.

Referring to the drawings, Arepresents the wad, which is formed of adisk of suitable material, with a central opening, a, being thus of theform ot' an annulus. When the wad is used without a cartridge, powder ispoured into (No mode/Ll the barrel and a solid wad,M B, introducedthereagainst. A wad, A, is then driven in against the wad B, the ball(shown spherical) next applied, and anotherwadA forced against the ball,it being noticed that the opening at either end of the wad is adapted tobe placed neit to the ball.

For cartridges, the powder, wads, and ball are applied to the shell in amanner similar to 4o that described above, and it will be seen that ineither case the ball is centered in frontand rear, and thus caused to bedischarged true and effective.

In cases where a conical ball is employed the annular wad is applied tothe point of the ball, and the force employed in thusy applying the wadserves to center the ball similar to a spherical ball.

Having thus described my invention, what I 5o claim as new, and desireto secure by Letters Patent, is-

The combination, with a spherical ball, ot wads ofthe form of annuli,each having a cylindrical opening, and one in front and the other in therear of said ball, and a solid wad behind the rear wad, and the shell,substantially as and for the purpose set forth.

WILLIAM T. CHAMBERLAIN.
